Prologue
Selary: The Legendary Super Saiyan. Only one appears every thousand years, making Selary the most powerful Saiyan in existence. However, despite Selary's immense strength it was found he was remarkably childlike. A trait rare in saiyans, although occasionally occurring. The saiyans of the time found this weakness and worked frivolously to exploit it. At this time, the Tsufuru were still more powerful than the saiyans on planet Plant, and the situation was growing dire. Able bodied saiyan men, the core of the Saiyan Empire, died by the dozen every day to the Tsufuru's advanced weaponry. So the saiyan elders decided it was in their best interests to use this Legendary Super Saiyan to fight against their enemies. Alone, he wouldn't stand a chance. He was strong to be sure, but a fighting force large enough would be able to defeat him. So instead of sending Selary by himself to fight the Tsufuru, they instead decided to breed him.
Selary quickly became an item amongst saiyan women, and over the course of his lifetime (twenty-three years) he was assumed to have fathered over seven hundred children. These children weren't born with the natural Super Saiyan ability as Selary was; instead they had to be trained to attain it. The Tsufuru saw this situation developing and decided to put it to a halt. They launched a massive attack force targeted to attack Selary. The battle lasted for hours, and it pitted nearly three dozen saiyan warriors against over three hundred Tsufuru tanks, planes and foot soldiers. In the end seventeen Tsufuru men remained, leaving all of the bodyguards, and Selary, dead or dying. However, within ten years of his death over 150 Super Saiyan warriors massed an attack against the neighboring population. The battle ended within six months, with the saiyans emerging victorious.
Throughout the centuries the Super Saiyan trait has not been lost among saiyans, although some don't possess the gene at all. A new caste system emerged with the new Super Saiyan addition. As always, a saiyan was branded with his rank when he was born, by gauging his power level. There were five levels of Saiyan: 3rd Class Warrior, 2nd Class Warrior, 1st Class Warrior were the most common. However an additional two remained: *Giji Saiyan and Super Saiyan. Giji Saiyan was the more common of the two, as it occurred when a Super Saiyan and regular saiyan had offspring together. Super Saiyans on the other hand were extremely rare. Both parents had to have the Super Saiyan gene, which happened less and less frequently as time went on.
A thousand years after the defeat of the Tsufuru the Saiyan Empire thrived. Fifty years before now a tyrant by the name of King Kold attempted to subdue the saiyans, only to have him and his two sons defeated by the current King Vegeta. Despite having immense power, the saiyans had never found a way to leave their own planet. After the defeat of the Kolds, the entire Saiyan Empire came under control of all territory once belonging to their adversaries. While this was a great jump forward for all saiyans, it created a civil war many years down the road. A new saiyan was born called Kakkorot, who showcased the ability to transform early in his life, and because of this was called back from his mission to earth. During the time he would have spent there, he stayed on Planet Vegeta, tutoring with King Vegeta's son, Prince Vegeta. Despite objections by the young prince, the two trained together well into their teenage years.
Unforeseen by anyone in the entire empire, Kakkorot had been slowly amassing supporters as the years went by. By the time he was twenty two he decided it was time to strike and led a vicious assault team against the King Vegeta, carefully planned to occur while the prince was away. Both sides seemed evenly matched, however, the King had become slack in his old age and was noticeably weaker than his son's counterpart. In the end Kakkorot secured his faction's victory, but not in time to prepare for an assault by Prince Vegeta. They battled for several months before Kakkorot and his followers were driven off Planet Vegeta into deep space. This was not the end of them, however, and even now they continue to make war with the Saiyan Empire, attempting to gain control of it.
